IMPROVED MEAT-CUTTER.

Specification forming part of Letters Patent No. 79,902, dated July 14,1868.

.To all whom it may concern.'

Be it known that 1,0. A. FOSTER, of Fitchburg, in the county ofWorcester and Gommonwealthof Massachusetts, have invented certain newand useful Improvements in Meat-Choppers; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, forming a part of thisspecification, and in which- Figure l represents a perspective view ofmy improved meat-chopper. Fig. 2 represents a section on line A B, Fig.1;'and Fig. 3 represents a section on line U D, Fig. l.

To enable those skilled in the art to which my invention belongs to makeand use the same, I will proceed to describe it more in detail.

In the drawings, A represents the base of the frame, to whicharefastened the side pieces, B B', the upper ends of which are slottedout horizontally, as shown at a a, to receive the pins or projectingends b b of the cross-piece C, which is -between the side pieces, B B',and from the top of which rises the standard D, from the top of whichprojects the stud o, the outer end of which is turned down to passthrough the slot d in the knife-operating arm H, which is held upagainst the shoulder on the stud by a Washer, e, fastened to the end ofstud o.

E is the main operating-shaft, one end of which rests in a slottedbearing in the standard F, being held in place by the pin f, whichpasses through the ears 1l. The frontof shaft E passes through and hasits forward bearing in thek cross-piece C. The front end of the shaft Epro- -jects through piece C far enough to enter the hubofthe slottedwheel G, to which it is fastened. The face of wheel G has two slots, gg, cut or formed in its face, said slots crossing each other at rightangles to eachother. Each slot has a groove, 2, cut on each side, asshown in Fig.

' 1, to receive the flanges of the sliding blocks bottom of the knife atthe proper height aber e the bottom z' of the meat-tub K it is securedby the set-screw 5. Motion being imparted to shaft E by crank L orotherwise to move wheel G in the direction indicated by the arrow, Fig.2, a back, up, forward, and down motion will be imparted to the knife Jtwice at each revolution of wheel G and shaft E, and which motion ispeculiarly adapted to the cutting ofv meat and vegetables. The blocks 3work back and forth in their respective grooves or slots in the wheel Gto give the said motions to arm H and knife J. The upper block neverdescends, however, below the center of wheel G, nor thelower one abovethe center of the wheel. The slot d in arm H admits of a free movementof the latter upon the stud o. t

The motion is easy and the cutting action of the knife very efcient. Themeat-tub K is placed upon a table, M, which turns on a pivot,

6, in the base A. The outer edge of the table M is provided with aratchet-wheel, N, into which the pawl m works, said pawl being hinged tothe lower end ot' lever O, which in turn is hinged at 7 to the side ofstand F. rI he upper end of lever O is acted upon by the cams or dogs 8on shaft E. A spring, 9, is

fastened to stand F, the lower end of which Y he seen that by therevolution of shaft E the meat-tub will be gradually revolved, while arapid back, up, forward, and down motion will be imparted to the knifeJ, while at the same time the meat-tub Kwill be gradually revolved tobring the meat or other material to be cut under the knife J, which isarranged to play near one side and just over the stationary scraper I?,which rests on the bottoml of the tub K, being held in place by its armn, which fits into a narrow slot cut in the front of piece C. Said arm nis provided with a pin, o, which passes down back of the ear 1l of thepiece l2 when the scraper is dropped or lowered into place, as shown inthe drawings. L

Arm a is held by the above devices so that it supports securely thescraper P when the cut ter or chopper is in operation, While the scrapercan be quickly removed, when desired, by sirnply lifting it up so as tofree pin o from the ear l1. The tub revolves so as to move the meat orother material Which is being chopped against thc point 13 of thescraper, Where-by the meat is turned in under the knife, thus insuring aperfect and uniform cutting or chopping of the meat or other materialplaced in the tub K. The tub K is retained in place on the table M bymeans of strips p, fastened to the table, and which project up upon theinside of the bottomof the tub, as indicated in Fig. 2. By simply takingout pin f, shaft E and cross-piece C, together with Wheel G and knife J,can all be removed from the stands B B and F.

Having described my improved meat-chopper, what I claim therein asnew'and of my invention, and desire to secure by Letters Pat ent, is-

1. The combination of the chopping-knife, its slotted arm H, and slidingblocks et with the grooved Wheel in which said blocks move and the pinupon which the said arm is hung, substantially as and for the purposesshown and set forth.

2. The combination of the chopping-knife,

its vibratory arm, and the grooved or slotted Wheel for actuating thesame, With their supporting-frame arranged to overhang or extend acrossthe revolving meat-tub, substantially in the manner and for the purposesshown and described.

3. The combination, with the cross-piece C and stands B B and F, ofshaft E, Wheel Gr, stand D, stud c, and arm H, substantially as and forthe purposes set forth.
